Humphrey Circles As Another Whale Enters Bay

ANTIOCH, CALIF. — Humphrey the humpback whale swam circles in inland waters for the 22nd day Friday as another whale swam into San Francisco Bay, more than 40 miles to the west.

Biologists said it is not unusual for whales to enter the bay at this time of the year during their southern migration from the Arctic, although none is known to have stayed in fresh water as long as Humphrey.

The Coast Guard said the newcomer is a California gray whale. A spokesman for the whale watch said it was not expected to join Humphrey.
